American Airlines Airbus A319 seat map

American Airlines' Airbus A319-100 (ex-US Airways sub-fleet, the type's largest operator). FLEET: American Airlines Group's FY2025 SEC Form 10-K reports 132 Airbus A319 mainline aircraft (21 owned / 111 leased) at an AVERAGE of 128 seats and average age 21.7 years as of 2025-12-31, with no cabin split. Wikipedia's American Airlines fleet table (neutral) is the citable source for the per-cabin split: 8 First / 24 Main Cabin Extra / 96 Main Cabin = 128 seats (126 shown in service, marked "Largest operator"); the 10-K's exactly-128 average confirms essentially the entire fleet is this single 128-seat configuration. Wikipedia notes the A319 is "being reconfigured with more first class seats" (a denser layout with more First is rolling out per the cited One Mile at a Time reports); that successor config is not yet materially in service (10-K average is still exactly 128), so only the current 128-seat config is modeled here. PER-CABIN COUNTS (8 / 24 / 96) are Wikipedia's citable figures; the "8" domestic First cabin sits in the same table column as the A321's citable "20 First" (see aa-321-190) and is American's two-cabin domestic First, modeled canonicalTier first. Main Cabin Extra is American's extra-legroom economy PRODUCT, not a physically contiguous cabin (forward Main rows plus the over-wing exit row, sold at a fee), so per AUTHORING section 6 it is modeled as a ZONE inside the single Main Cabin with seatType aa-mce (canonicalTier extra_legroom_economy). ROW GRID IS DERIVED, not a placard scan (aa.com hard-403s bots; competitor seat-map sites are prohibited). Derivation: First 2-2 (A/C/D/F) rows 1-2 = 8; a forward galley/lavatory class divider occupies the unnumbered gap; Main Cabin 3-3 rows 8-27 = 120 = twenty full six-abreast rows (no partial rows needed — 8/24/96 divide cleanly by six). The A319 airframe has a SINGLE over-wing exit pair each side (Type III), unlike the A320/A321 which have two over-wing exits; exit-pair placement, wing span and the forward/aft monument positions are DERIVED from the identical Delta A319 airframe geometry (see dl-319-132) and may differ from the physical aircraft. MCE zone = forward rows 8-10 (18) + the single over-wing exit row 14 (6) = 24; standard Main fills the remainder (rows 11-13 and 15-27) = 96. windowAlignment left "unknown" on all window seats (derived grid). aircraft.windowGridType intentionally omitted: no a319 engineering grid exists in data/window-grids/, and the longer A320-family grids describe a different fuselage/door geometry, so binding one would not correctly place A319 window blanks. American does not publish A319 pitch/width in any citable source (aa.com is bot-blocked), so all pitch/width values are flagged approximate/unsourced.
